FILM OR SHEET WITH PHOTOCATALYST FOR WALLPAPER

摘要

PROBLEM TO BE SOLVED: To provide a film or sheet with a photocatalyst for wallpaper which enables disposition of photocatalyst particles in a high density on the surface of the wallpaper and of which the base is not corroded by the action of the photocatalyst.

SOLUTION: The film or sheet 1 with the photocatalyst for the wallpaper is constituted by laminating sequentially a plastic film or sheet layer 2, a primer layer 3 and a photocatalyst thin film layer 4. The film or sheet layer 2 is formed preferably of a film or sheet of which the elastic modulus is 100 MPa or above at 80-130°C and 100 MPa or below at 150-190°C. The elongation in drying can be suppressed, while the fracture of the photocatalyst particle can be reduced, and also a rugged pattern can be formed beautifully.
